Can knock sensor cause rough idle?
If this sensor isn’t working correctly, it can cause a lot of problems for your car. Most bad knock sensor symptoms are easy to detect, as you will notice bad acceleration and a rough engine idle, but some are more subtle like bad fuel damage and catalyst damage. via
Can a bad knock sensor cause a misfire?
Knock sensor problems can also be accompanied by other symptoms. When the engine is started, the vehicle will shake or vibrate, causing a misfire. As a result of the detonation of the cylinders, the engine may emit strong exhaust and burning smells. via
What causes a knock sensor code?
Code P0325 means that your car computer detects a problem with the knock sensor unit or its circuit. The knock sensor detects the vibrations from abnormal combustion, known as spark knock. A car can have one or two knock sensors depending on its make and model. via
How do you bypass a knock sensor on a Subaru? (video)
